Bones store most of the calcium supply of the body.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Bones store most of the calcium supply of the body because calcium is an essential mineral for bone health and strength. Calcium is constantly being deposited and withdrawn from the bones to maintain proper levels in the bloodstream, which is necessary for various bodily functions. When calcium intake is insufficient, the body will extract calcium from the bones to meet its needs, potentially leading to weakened bones and an increased risk of osteoporosis. Therefore, it is true that bones store a significant amount of the body's calcium supply.Rate this question:
